CAUTION
At the output port which has simulatively serialized the parallel I/O, any output
does not vary even if the reset command is executed.

CAUTION
If the return-to-origin completing operation selection parameter (single-axis
controllers:PRM33, dual-axis controllers:PRM2) is set to 1 or 3, DO4*

The head program is the program selected by switching the program which is finally
executed at HPB or POPCOM.
The head program is also switched when the communication command "@SWI" is
executed. Moreover, when the program data is loaded from the memory card to the
controller, it is sometimes switched.
*1: DO0 to DO4 when the SRCP/SRCD series controllers are used.
*2: DO5 when the DRCX series controllers are used.
*3: DO3 when the SRCP/SRCD series controllers are used.
